Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00068 | $0.04055 |
| Opus 5 | $0.00034 | $0.02027 |
| Sonnet 5 | $0.00014 | $0.00811 |
| Haiku 4.5 | $0.00007 | $0.00405 |
Grade A, and why
ecom-listing-copywriter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Product Listing Copywriter — E-Commerce Product Detail Page Knowledge Base
Helps users write professional e-commerce product listing copy covering four core modules — title, key selling points, specifications, and FAQ — tailored to the style guidelines of Taobao, JD.com, and Amazon.
Quick Start
The user only needs to provide:
- Product Information: Category, brand, model, core specs
- Target Platform: Taobao / JD.com / Amazon (or generate for multiple platforms at once)
- Target Audience: Gender, age range, usage scenarios
- Language: Chinese / English / Bilingual
- Differentiators: Core advantages over competitors (optional — user-supplied or extracted from the provided information)
Example:
"Write product listing copy for a wireless noise-cancelling headphone. Brand is SoundMax, model Pro X3, key features are noise cancellation and long battery life. I need both a Taobao and an Amazon version."
1. Platform Style Comparison Matrix
1.1 Core Rules Across Three Major Platforms
| Dimension | Taobao/Tmall | JD.com | Amazon |
|---|---|---|---|
| Title Length | ≤60 characters (mobile: prioritize keywords in first 30) | ≤75 characters (recommended ≤45) | ≤200 characters (recommended ≤80 for front-end display) |
| Title Style | Keyword stacking + marketing terms, trending keywords first | Brand + Category + Core Specs + Scenario, clear structure | Brand + Core Feature + Product Type + Key Spec, no promotional terms |
| Selling Point Format | Hero image text + long-form detail page | Product intro + structured spec table | Bullet Points (5 items, each ≤500 characters) |
| Selling Point Tone | Emotional, evocative, scenario-driven ("Save your commute") | Rational, spec-driven, authority-backed ("XX Certified") | Feature-Benefit structure, concise and professional |
| FAQ | "Ask Everyone" section / bottom of detail page | Product Q&A section | Product Q&A Section |
| Spec Table | Free-form, often embedded as images in the detail page | Structured spec table (platform template) | Product Information structured fields |
| Prohibited Words | Superlatives like "best," "first," "absolute" (Advertising Law) | Same as Taobao + false advertising terms | "best seller," "#1," "guaranteed," and other exaggerated claims |
| SEO Focus | Trending keywords, long-tail terms, attribute terms | Category terms, brand terms, function terms | Backend Search Terms field + title keywords |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
